My present inventionl has reference to furniture casters and has for its object to provide a simple economical means for vertically adjusting the caster to compensate '5 for variations in the lengths of furniture legs, whereby such furniture can be micrometrically leveled.

Another object of the invention is the provision of means for holding the caster steady in the adjustable member.

With the above and other objects in view the invention consists in certain peculiari-l ties in construction and combination of parts which will hereinafter be set forth withparticularity in the accompanying drawing and specifically pointed out in the appended claim.

In the drawing:

Figure 1 is a side elevation of the improvement in applied position, the 'leg for the furniture being in section.

Figure 2 is a side elevation of the socket and the adjustable element therein in section. s 45 Figure 3 is a similar view showing the sleeve as well as the `fixed socket in section.

Figure l4 is a view of the adjustable element. v

Referring to the drawing in detail, thenu- $0 meral 1 designates the leg of any desired article of furniture, and let in the leg from the bottom thereof there is the tubular member that comprises the socket 2 of the improvement. The socket has its lower orouter end Hanged, as at3, and the said flanges-provided with openings for the reception of securing means, such as screws, that enter the bottom of the leg 1. The socket 2 is interiorly threaded throughout its length. Threaded L0 for vertical adjustment in the socket 2`there is a stop member 4. The stop member may have both of its opposite faces kerfed, as at 5,

for the reception of the bit -of a screw driver whereby the stop member 4 may be properly adjusted in the/socket 2. The caster isindicated by the numeral 6 and the shank or stem therefor by the numeral 7. The outer end of the stem 7 is enlarged or headed to provide the same with an inner shoulder 8.

Jo The' numeral'9 designates the adjustable before,

\1 member of the improvement. The member 9 is in the nature of a tubular sleeve and receives in the bore thereof the `stem 7. The outer end of the sleeve 9 is formed .with an outstanding flange 10. When it is found desirable to prevent the caster wheel from turning, the fiange 10 is provided onits outer face with V-shapedl notches 11 to receive therein cross sectionally V-.shaped lugs 12 on Vthe caster at the juncture of the shank 7. W

rIhe sleeve 9 is eXteriorly threaded, as at 13, throughout 'its length.- The inner end of.. the sleeve is closed, but the said sleeve, from" its said closed end, is cut away at points ladjacent to its sides to provide the same with a central reduced extension 14 and with iingers 15 which are disposed below the top of the central extension 14. The side walls provided by the fingers are 'cut at opposite angles, as disclosed by the drawing, so that the outer ends of the fingers are materially reduced which renders the fin ers readily susceptible to bending. These ngers, after the stem 7 of the caster 6 isreceived through the sleeve arekben't inwardly to contact with 75 Y the shoulder 8 of-the stem 7 and whereb the sleeve 9 is rotatablysupported but held rom longitudinal nmvement on the stem 7, when the interengaging lugs 12 and notches 11 are not employed. After the distance be- B0 tween the floor and the socket has been ob tained the stop element 4-is adjusted in the socket so 'that the same will be in position to be contacted by the inner closed end of. thejsleeve 9 when the S`ame^is screwed in the 85 socket. This adjustment may be obtained the socket is inserted in the leg of the furniture if desired, and the adjustment of the caster can be readily made by any one without resorting to askilled mechanic, and 90` when so adjusted the tension between the parts will hold the caster in properly ad- )usted position.

1t is thought from the foregoing description the `novel features of my invention will be readily apparent but it is to be understood lthat I do not wish to be restricted to v the precise details ofv construction herein set forth and ray make changes in the-construction an' combination andarrangement of the several parts providing such changes fall Within the scope of what I claim.

Having described the invention, claim:

A caster `mounting including a caster stem having an enlargement at one end tooform an annular shoulder, an exteriorly threaded sleeve mounted on the stem and having a closed end With the enlargement of the stem in abutting engagement therewith, said sleeve having cut-out portions in opposite Walls adjacent the closed end to provide fingers bendable to engage the annular `shoulder for cooperating With the closed end in rotatably securing the sleeve to the stem, a flange on said sleeve and having notches,

.teeth on the-stem to ride into-and out of the notches during rotation of the sleeve on the stem, an internally threaded anchoring sleeve having the iirst sleeve threaded there in, and a stop for limiting the threading of the rst sleeve into the anchoring sleeve and threaded inthe latter to vary its location Within said anchoring sleeve.
